How to Use Codex + Image2 for a Controlled, Editable AI‑Generated PPT – Step‑by‑Step Guide

This article presents a four‑stage workflow that uses Codex to extract content, Image2 to explore visual styles, high‑resolution visual drafts, and a mixed‑reconstruction strategy to produce fully editable PPTX files, complete with prompt examples, validation criteria, and common pitfalls.

How to Use Codex + Image2 for a Controlled, Editable AI‑Generated PPT – Step‑by‑Step Guide

Why a Structured AI PPT Workflow Matters

Generating a PPT with AI is easy, but creating a professional, editable presentation requires a disciplined pipeline that separates content, style, visual drafts, and final PPTX reconstruction.

Stage 1 – Content Extraction (Let Codex Read the Document)

Upload the source document and ask Codex to produce a 20‑page outline without creating a PPT file. The outline includes page titles, core statements, bullet points, key data, and visual suggestions.

请阅读我上传的文档,先不要生成 PPT 文件。
请先帮我生成一份 20页 PPT 的内容框架,每页包括:
1. 页标题
2. 一句话核心观点
3. 正文要点
4. 可以放进页面的关键数据/关键词
5. 视觉建议:这一页适合用数据卡片、流程图、对比图、图片页、时间线还是总结页
要求:
- 内容必须围绕上传文档,不要脱离材料自行发挥。
- 如果资料不足,请标注“待补充”,不要编造事实。
- 标题要像正式汇报标题,不要像论文目录。
- 每页都要有清楚的结论,而不是只罗列信息。
- 输出完成后等待我确认,再进入视觉设计阶段。

Stage 2 – Visual Style Exploration (Generate Style Previews with Image 2)

After confirming the outline, generate several complete PPT style previews (A, B, C, D) using Image 2. Each preview is a low‑cost visual mock‑up that lets you compare style consistency, information density, and suitability for the target audience.

请基于已经确认的 PPT 大纲,调用 imagegen 生成三套完整 PPT 拼图预览:方案 A、方案 B、方案 C、方案 D
输出要求:
1. 每套方案都包含完整 20页 PPT 的缩略预览,并保持页码顺序。
2. 三套方案必须明显不同,不要只是换颜色。
3. 每套方案内部必须统一,包括字体层级、配色、图标风格、卡片样式、背景风格、页脚页码和整体信息密度。
4. 每个缩略页都必须是 16:9 横版 PPT 页面。
5. 文字可以适当缩小,但主标题、关键数字、核心图表和页面结构必须能看清。
6. 不要生成 PPTX 文件,不要输出长篇解释,只输出三套拼图预览。

Style preview B
Style preview B

The three‑stage preview helps you decide which visual direction best fits the reporting scenario (internal brief, client roadshow, or training).

Stage 3 – High‑Resolution Visual Drafts (Upscale Each Slide)

Choose the preferred style and upscale each thumbnail to a single‑page high‑resolution visual draft. This step provides a clear “blueprint” for the final PPTX and avoids the loss of detail that occurs when using low‑resolution thumbnails.

请把我选中的 PPT 拼图方案,按页码顺序逐页放大成单页高清视觉稿。
要求:
1. 每次只输出一页,不要输出拼图,不要一次输出多页合成图。
2. 每页都是 16:9 横版,适合作为后续可编辑 PPTX 的复刻蓝本。
3. 严格沿用选中方案的视觉系统,包括字体气质、字号层级、主色、辅助色、图标风格、卡片样式、背景风格、页脚页码和整体信息密度。
4. 每页主标题、核心观点、关键数字、图表标签、页码必须清晰可读。
5. 不要新增拼图里没有的品牌、Logo、人物、产品或数据来源。
6. 如果小字无法准确识别,请参考已确认的大纲补全,不要编造事实。
7. 这一阶段只输出单页视觉稿,不要生成 PPTX 文件。

Stage 4 – Editable PPTX Reconstruction (Mixed‑Reconstruction Strategy)

Convert the high‑resolution visual drafts into an editable PPTX. Complex images, textures, and intricate charts are kept as pictures, while titles, body text, key numbers, labels, conclusions, and page numbers are rebuilt with native PowerPoint text boxes and shapes.

请根据这些单页高清视觉稿,生成一份可编辑 PPTX。
核心目标:采用“复杂视觉保真 + 主要信息可编辑”的混合还原策略。
必须可编辑的内容:
1. 主标题
2. 副标题
3. 正文要点
4. 关键数字
5. 图表标签
6. 结论句
7. 页码和页脚说明
可以保留为图片的内容:
1. 复杂照片
2. 纹理背景
3. 难以复刻的装饰元素
4. 复杂插图
5. 不需要经常修改的复杂图表背景
硬性要求:
- 不要把整页直接贴成一张图片。
- 不要为了全量可编辑而把页面做成低质感模板。
- 如果原图文字需要替换成可编辑文本,请先遮盖原文字,再叠加 PPT 文本框。
- 所有页面保持统一字体、颜色、边距、页脚和页码规则。
输出要求:
1. 输出 PPTX 文件。
2. 同时输出每页 PNG 预览图。
3. 输出视觉对比图,方便检查还原质量。
4. 最后说明哪些元素是可编辑的,哪些元素保留为了图片。

Validation Checklist – Ensure the PPT Is Truly Editable

Can the file be opened in WPS or PowerPoint without errors?

Are titles, subtitles, body text, key numbers, labels, and page numbers double‑click editable?

Are page numbers and legends separate text objects rather than embedded in images?

Is the visual style consistent across all slides (fonts, colors, margins)?

Do the exported PNG previews match the on‑screen appearance?

Is there any slide that is a full‑image screenshot instead of editable content?

Are complex visual elements kept as images only when necessary, without hindering later edits?

Following this workflow prevents the common failure where AI‑generated PPTs consist of static images that cannot be edited, ensuring the final deliverable is both visually polished and practically usable.
